Question

Define wave lenght timeperiod and frequency

Answer 1

Answer:

WAVE LENGTH :- the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is thus the inverse of the spatial frequency.

FREQUENCY :- Frequency is the number of occurrences of a repeating event per unit of time.

TIME PERIOD :- Space of seconds, minutes, hours, days, weeks, months or years with an established beginning date and ending date. It's a unit of measurement used to categorize a length of time. Also called timeframe.

Answer 2

Define :-

1. Wave length

• The distance between two consecutive compression and two consecutive rarefaction is called wavelength.

• It is denoted by $\lambda$ (lambda)
• Its S.I unit is metre.

2. Time period :-

• The time required by a wave to execute one complete oscillation is called time period.

• It is denoted by the letter T.
• Its S.I unit is second.

3. Frequency :-

• Number of vibrations completed in one second is called frequency.

• It is denoted by the letter f.
• Its S.I. unit is (Hz) hertz.
